株式会社うるる Tech Stack

Crowdsourced data platform for bid intelligence and distributed work

Information Technology & Services 中央区晴海, 東京都 201–500 employees Public Company

Uluru operates a two-sided marketplace: Shufti (crowdsourcing platform) supplies labor; NJSS (bid intelligence service) consumes it. The tech stack is polyglot (Laravel, Rails, Python, Node.js across backend; React frontend) with heavy reliance on search infrastructure (Elasticsearch, OpenSearch, Solr) — a signal that data volume and query complexity are core operational constraints. Active projects reveal a company mid-migration: moving from monolithic architecture toward microservices, improving crawler accuracy, and embedding AI into the crowd-worker pipeline. Senior-heavy hiring (11 of 16 open roles) focused purely on engineering suggests technical debt and scale challenges are the primary hiring drivers.

About 株式会社うるる

Uluru is a Japan-based public company (listed on Tokyo Mothers in 2017) that operates a crowd-generated service (CGS) business model combining crowdsourced labor with information products. The core platform is Shufti, a crowdsourcing marketplace with 370,000+ registered workers; it feeds NJSS, an enterprise bid intelligence service that aggregates public procurement data from government and municipal bodies across Japan. NJSS maintains a database of 9 million+ historical bid records collected by crowd workers — achieving coverage depth that traditional web crawlers cannot. The company targets mid-market enterprises and government procurement professionals seeking comprehensive bid tracking. Revenue model combines commission-based crowdsourcing (Shufti) with subscription licensing for NJSS.
